量子簇代数中的F-多项式

F-polynomials in Quantum Cluster Algebras

Thao Tran

摘要:

Fomin和Zelevinsky定义了F-多项式和g-向量,给出了一个用初始聚类数据表示聚类代数中聚类变量的公式。量子团簇代数是团簇代数的某种非对易变形。本文定义并证明了量子团簇代数的类量子F-多项式的存在性。我们证明了量子F-多项式的一些性质。特别地,我们给出了一个递推关系,可以用来计算它们。最后,我们计算了一类簇变量的量子F-多项式和g-向量,这类簇变量包括A型量子簇代数中的所有簇变量。

英文摘要:

F-polynomials and g-vectors were defined by Fomin and Zelevinsky to give a formula which expresses cluster variables in a cluster algebra in terms of the initial cluster data. A quantum cluster algebra is a certain noncommutative deformation of a cluster algebra. In this paper, we define and prove the existence of analogous quantum F-polynomials for quantum cluster algebras. We prove some properties of quantum F-polynomials. In particular, we give a recurrence relation which can be used to compute them. Finally, we compute quantum F-polynomials and g-vectors for a certain class of cluster variables, which includes all cluster variables in type A quantum cluster algebras.
